I just wanted to let people know that some apps can be accessed while the the screen is locked. The music player is one. If you lock the screen , a press of the end key will let you pause, play, forward and back the song. Another thing I noticed is if I have the text app open, lock the screen and get a call, when the caller ends the call (me using earbuds with a mic and not pressing anything on my phone) the screen goes back to the open text window and is not locked. It creates the possibility for blank texts to be sent to the last person you were texting.
